Out Of Range/No Antenna - Dexcom SEVEN PLUS User Manual

HELPFUL HINTS:
• If you see the "???" in the Status Box of the Receiver Trend Graph, it is recommended that you
wait out this period of time. Do not calibrate your system during this time.
• When you see "???", taking fingersticks with your meter and entering them does not help the
System display more glucose readings. Any fingersticks
that you take during "???" will be ignored by the System.
• Wait until you see a single blood drop in the Status Box before entering a calibration value into
your Receiver.
5.4.4

OUT OF RANGE/NO ANTENNA

When you see the Out of Range Symbol in the Status Box instead of a glucose reading, this
•
means the Receiver has "missed" the last glucose reading sent by the Transmitter.
No Glucose Data
Once you have moved the Receiver closer and waited 5-10 minutes, the Out of Range Symbol
•
in the Status Box should go away. The Antenna Symbol should reappear in the lower right
corner, and you should receive a glucose reading in the Status Box.
If you are still having trouble receiving System readings because of this
•
problem, contact DexCom Technical Support at 1-888-SEVENGO (738-3646).
HELPFUL HINTS:
• You can set an Out of Range Alert to notify you when the Receiver and Transmitter are not
talking (see Chapter 2, Section 2.3.4, "Setting Out of Range Alert"). You can set the amount of
time the Transmitter can be out of range before the Receiver alerts you.
• The Transmitter and Receiver may lose communication during the following circumstances:
While you are lying on a waterbed, while they are near metallic objects, or when you are using an
electric blanket.
• If you see this Symbol, make sure the Receiver is within 5 feet
of the Transmitter/Sensor Pod. If it is not, move the Receiver
closer and wait at least
5 minutes.
NOTE: The Antenna Symbol in the lower right corner
will disappear.
